QI have tried to grow ‘Patio Star’ courgettes, but each time they have failed. The fruits start well but then they soften and rot. Can you tell me what I am doing wrong?

AThe usual reason for the failure of courgette crops is lack of pollination. Bees and other insects normally do this. The solution is to hand-pollinate blooms.
Simply remove a male flower, which has a long unswollen stalk, and dab a pollen-laden anther onto a female stigma. Alternatively, you can use a soft paintbrush to transfer the pollen in the same way.
